Bradford, without knee injury victims Matty Blythe and Adrian Purtell, and further hampered by the loss of influential full-back Brett Kearney with a shoulder problem, scored tries through Keith Lulia and Danny Addy.

The Broncos began encouragingly by forcing the Bulls to carry the ball into touch on the opening play of the game and then defend two successive drop-outs from under their own posts.

Bradford resisted the early pressure and almost took the lead when Elliot Kear crossed in the corner but was adjudged to have put a foot in touch.

London should then have gone ahead but centre Howell dropped Soward's pass with the line beckoning.

In what became a saga of repeated handling errors from both sides, the deadlock was finally broken when James Woodburn-Hall put Howell through a gap four minutes before half-time. The Australian scrum-half failed to master a cold and blustery wind and missed the conversion.

Caton-Brown was then hauled down just metres short as the hooter sounded to leave the visitors four points up at the break.

Seven minutes into the second half another handling error, a Broncos knock-on, gave Bradford the platform to respond as Lulia muscled his way over near the corner flag with Jamie Foster expertly adding the goal from the touchline to edge the Bulls ahead.

The Broncos regained the lead when Howell rose to claim and ground a perfectly weighted Soward kick.

This time Soward had no trouble adding the extras and barely two minutes later he was sprinting away from the halfway line, having intercepted a stray looping pass from Luke Gale.

The Broncos virtually sealed the long-awaited victory when Caton-Brown, who has played most of the season on dual registration with Championship One Hemel Stags, crossed in the corner from a Kieron Dixon pass.

Although Addy claimed a try back for the Bulls, it was not enough to change the result.

Soward blotted his copy-book by being sin-binned for needlessly kicking the ball off the tee as Foster lined up the conversion attempt.
